Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to barbecue synthetic charcoal used for outdoor cooking.

[0002]

[Prior art]

 Charcoal is a fuel that steams wood to carbonize it.In the past, it was consumed in large amounts in ordinary households for cooking or heating.In recent years, however, the spread of gas fuel and the use of heating appliances Due to its widespread use, charcoal is almost no longer used as fuel or heating in ordinary households.

However, recently, the so-called outdoor life has become extremely popular, and charcoal has come to be used as a fuel for outdoor cooking such as camping. However, many of the younger generations who have never enjoyed outdoor life have never used charcoal as fuel, which results in struggling to ignite charcoal and create a charcoal fire.

The ignition point of charcoal is said to be 250 to 450 ° C., but when it reaches that temperature, it does not ignite immediately, but if this temperature is not maintained for a certain time, the charcoal cannot be ignited. In order to ignite charcoal and cause charcoal, it is necessary to put charcoal on a burning or quick igniter such as wood or newspaper, and to ignite it. It may get burned, or only the ignition material may burn, and the charcoal may not ignite, so some tips are needed.

[0005] Therefore, regarding the ignition of charcoal for outdoor cooking, a method of attaching a torch lamp to a cassette gas cylinder and directly blowing the fire of the torch lamp to the charcoal to ignite the charcoal or a bottom made of a wire mesh is used. The method is to put charcoal in a charcoal raiser like a one-handed pot, place it on a single burner and ignite it directly. However, since these methods require special equipment to produce a charcoal fire, various disposable charcoal igniters are commercially available. For example, a solid fuel type (for example, a mixture obtained by kneading a chemical igniting agent and carbon powder into a solid), a brush containing kneading brush-like fuel applied to charcoal, or a spray type is used.

[0006]

[Problems to be solved by the device]

 However, in the case of the solid fuel type in which the above chemical ignition agent and carbon powder are kneaded into a solid, incomplete combustion occurs at the beginning of ignition, so smoke is emitted and a chemical odor rises. There is a problem that the atmosphere is destroyed and at the same time, the taste of cooking is impaired. Furthermore, after igniting a charcoal fire, the arrangement of charcoal must be constantly changed in order to maintain the desired firepower, but it is difficult for the younger generation who is not accustomed to handling charcoal to maintain the desired firepower. Not only that, there is also the inconvenience of extinguishing the charcoal fire that has just happened.

The present invention has been made to solve the above-mentioned problems of an ignition agent for disposable charcoal and the above-mentioned problems of handling a charcoal fire after ignition, and it is easy and easy to ignite. It is possible to clearly confirm that the fire has occurred, and it is possible to surely cause a charcoal fire, and since the combustion from the beginning of the ignition is active, it is possible to quickly ignite the charcoal fire without producing smoke or a bad odor, and even after the ignition, there is no need to do anything The purpose is to provide a synthetic barbecue for barbecue that can maintain a sufficient level.

[0008]

[Means for Solving the Problems]

 The inventor first conceived to combine the ignition material and the coal for fuel. Next, we conducted intensive research in order to facilitate the ignition of the ignition material and to promote the combustion of the fuel coal. As a result, the ignition material is accommodated in the combustion chamber provided inside the synthetic coal for fuel with the air circulation space interposed, the lateral side of the combustion chamber, the exhaust hole on the upper side, and the exhaust hole if necessary. Then, by piercing each of the suction holes on the bottom surface, combustion of the ignition material occurs actively, and the fuel coal is ignited reliably and promptly, and at the same time, the combustion air flows into the fuel coal after ignition. The present inventors have completed the present invention by discovering that the appropriate combustion continues and that the firepower suitable for barbecue is maintained without any action after ignition.

The synthetic charcoal for barbecue according to claim 1 of the present invention is formed by forming charcoal powder, has a combustion chamber inside, a lateral hole communicating from the side surface to the combustion chamber, and the combustion chamber from the upper surface. A fuel charcoal provided with an exhaust hole penetrating through and a igniter was inserted in the combustion chamber with an air circulation space interposed, and the ignition end was exposed from the lateral hole by forming a gap in the lateral hole. Use as a summary.

According to a second aspect of the present invention, the synthetic charcoal for barbecue according to the first aspect, wherein the fuel charcoal comprises a box and a lid, and the inside of the box serves as a combustion chamber, and a side surface of the box. From this, the horizontal hole is communicated with the combustion chamber, a large number of suction holes are formed at the bottom of the box body, the exhaust holes are penetrated through the lid body, and the upper surface of the box body is covered. To do.

The synthetic charcoal for barbecue according to a third aspect of the present invention is the synthetic charcoal according to the first aspect of the present invention, wherein the combustion chamber and the lateral hole are integrally continuous and have a tunnel shape that penetrates the synthetic charcoal from a side surface. And The synthetic charcoal for barbecue according to claim 4 of the present invention is characterized in that, in the idea of claim 3, the exhaust hole is a slit and both ends are connected to the lateral hole.

The synthetic charcoal for barbecue according to a fifth aspect of the present invention is formed by molding carbon powder, has a combustion chamber inside, a lateral hole communicating from the side surface to the combustion chamber, and the combustion chamber from the upper surface. A fuel charcoal provided with an exhaust hole penetrating to the combustion chamber and an intake hole penetrating from the bottom surface to the combustion chamber, and an ignition material is inserted into the combustion chamber with an air circulation space interposed, and the ignition end is set to the lateral hole. It is characterized in that a gap is provided so that it is exposed from the lateral hole.

The fuel charcoal is obtained by mixing a carbon powder with a binder such as corn starch and compression-molding and slowly drying. The ignition material may be any material that can be easily ignited and is flammable.For example, a small lump made of wood-based material, which is made easily flammable by containing oil or hydrocarbon fuel, It is preferable to use a flammable sheet containing a fat or oil or a hydrocarbon-based fuel, which is formed into a tubular shape and packaged with an air circulation space inside.

Since the ignition end of the ignition material is arranged so as to be exposed from a part of the transverse hole of the synthetic coal with a gap provided in the transverse hole, when the exposed ignition end is ignited, the flame is emitted from the transverse hole. It is introduced into the combustion chamber together with the outside air that is taken in, and exhaust gas is exhausted from the combustion chamber through exhaust holes. Therefore, the ignition material does not generate smoke due to incomplete combustion in the early stage of combustion, and the flame rotates from the ignition end toward the ignition material in the combustion chamber.

Since the ignition material in the combustion chamber is inserted around the air circulation space, when the ignition material starts combustion, not only from the lateral holes but also the combustion material provided as necessary. Fresh air also flows into the combustion chamber through the intake holes at the bottom of the chamber, and the combustion gas is exhausted through the exhaust holes, so the ignition material burns with sufficient heat. Therefore, the fuel coal is ignited quickly and reliably.

That is, the ignition of the fuel coal first starts from the vicinity of the exhaust hole on the upper surface of the combustion chamber, then the ignition range is expanded to the entire combustion chamber, and finally the combustion proceeds to the bottom of the combustion chamber and to the entire fuel coal. . This situation will be described with reference to the sectional view of the fuel charcoal in FIG. 7. As shown in FIG. 7 (a), the ignition part 28 of the fuel charcoal first starts near the exhaust hole 22 on the upper surface of the combustion chamber, so that the portion near the burned material is located. The appropriate firepower will be generated from this, and you can start the barbecue quickly. Next, as shown in FIG. 7 (b), the ignition part 28 expands and the heating power increases, and at the same time, the surface of the ignition part 28 is covered with the ash portion 32, and an appropriate soft heating power is maintained. As the combustion progresses further, as shown in FIG. 7 (c), the surface of the ignition part 28 is covered with the ash part 32 and the moderately soft thermal power is maintained, and the ignition part 28 extends to the bottom of the combustion chamber 14 and the fuel. Combustion progresses throughout the charcoal.

As described above, the combustion of the fuel coal proceeds without any modification, but the combustion time of the fuel coal and its thermal power are the size of the fuel coal, the size of the combustion chamber, the quality of the fuel coal, and the composition thereof. It is determined by appropriately selecting the arrangement and size of the ratio, lateral holes, exhaust holes, suction holes, and the like. In addition, the intake hole at the bottom of the combustion chamber is provided as appropriate in order to obtain a particularly strong thermal power in a short period of time and according to the quality of coal.

[0018]

[Embodiment of the invention]

 Embodiments of the present invention will be described below with reference to the drawings. 1 is an exploded perspective view of a second embodiment of the present invention. First, 5% of corn starch was mixed with charcoal powder and kneaded with water to prepare a material for fuel charcoal, which was put into a mold and compression-molded, followed by drying, and as shown in Fig. 1, a box body was formed. A fuel charcoal 30 composed of 10 and the lid 12 was molded.

A combustion chamber 14 is formed inside the box body 10, and lateral holes 16 having upper surfaces open from both side surfaces communicate with the combustion chamber 14. A step portion 20 into which the lid 12 is fitted is provided at the upper end of the outer periphery of the combustion chamber 14.

The lid 12 is a plate having a size that fits into the stepped portion 20 of the box body 10, has a large number of exhaust holes 22 penetrating therethrough, and projecting pieces 24 covering the upper surfaces of the lateral holes 16 project on both sides. There is. The ignition material 26 is arranged so as to cross the combustion chamber 14 and fit into the lateral holes 16 at both ends, and the ignition end 26 a is exposed from the lateral holes 16. When the ignition material 26 is arranged, the lid 12 is fitted into the step portion 20 of the box body 10 to cover the upper surface of the box body 10 and the upper surfaces of the lateral holes 16 with the lid body 12. A sufficient air circulation space is provided around 24, and a sufficient gap is secured between the lateral hole 16 and the ignition material 14 so that air can flow in.

FIG. 2 is a perspective view showing an embodiment of claim 4 of the present invention. Similar to the embodiment of FIG. 1, the fuel charcoal 30 is formed integrally with a kamaboko-shaped mold by using the fuel charcoal material prepared by mixing 5% of the starch with carbon powder and kneading with water. The chamber 14 and the lateral holes 16 at both ends thereof are integrated in a circular shape having the same cross section, and the lateral hole 16 and the combustion chamber 14 laterally penetrate the synthetic coal in a tunnel shape. An exhaust hole 22 penetrates the lateral hole 16 and the combustion chamber 14 from the upper surface. The exhaust hole 22 has a slit shape and both ends thereof are continuous with the lateral hole 16.

Further, as shown in the cross-sectional view of FIG. 3, on the bottom surface of the combustion chamber 14, an igniter material 26 having a diameter smaller than that of the combustion chamber 14 and having a thickness capable of sufficiently maintaining the air circulation space is provided from the lateral hole 16 to the ignition end. 26a is inserted so as to be exposed from the lateral hole 16, and a sufficient gap is secured between the lateral hole 16 and the ignition material 14 so that air can flow in.

In each of the embodiments, the ignition end 26 a of the ignition material 26 is arranged so as to be exposed from the horizontal hole 16 with a gap provided in the horizontal hole 16, so that the exposed ignition end 26 a is ignited. Then, the flame is introduced into the combustion chamber 14 together with the outside air sucked through the gap of the lateral hole 16, and the exhaust gas is exhausted from the combustion chamber 14 through the exhaust hole 22. Therefore, the ignition material 26 does not generate smoke due to incomplete combustion at the initial stage of combustion, and the flame rotates from the ignition end toward the ignition material 26 in the combustion chamber 14.

Since the ignition material 26 in the combustion chamber 14 is inserted with the air circulation space around it, when the ignition material 26 starts burning, fresh air flows into the combustion chamber from the lateral hole 16. However, since the combustion gas is exhausted from the exhaust hole 22, the ignition material 26 burns while maintaining sufficient thermal power. Therefore, the fuel coal 30 was ignited quickly and reliably.

That is, the ignition of the fuel charcoal 30 first starts from around the exhaust hole 22 on the upper surface of the combustion chamber 14, and then the ignition range expands throughout the combustion chamber 14, and finally reaches the intake hole at the bottom and the entire fuel charcoal. Burns. Combustion of fuel charcoal proceeds without any particular modification, but the combustion time and its thermal power of fuel charcoal depend on the size and size of the fuel charcoal, the size of the combustion chamber, the arrangement and size of lateral holes, exhaust holes, suction holes, etc. Is appropriately selected. In particular, in the embodiment shown in FIG. 2, the initial ignition of the fuel coal is extremely rapid over the entire slit, which is the exhaust hole 22, and the ignition range is expanded. Although the exhaust holes 22 are continuous slits, a plurality of independent exhaust holes 22 may be arranged.

In the embodiment described above, the intake hole 18 is not provided at the bottom of the combustion chamber 14, but in the embodiment of claim 5 of FIG. 4, as shown in its exploded perspective view, A large number of suction holes 18 are formed in the bottom surface of the combustion chamber 14. Also, in the embodiment of claim 5 of FIGS. 4 and 5, the suction hole 18 is similarly formed in the bottom surface of the combustion chamber 14. Combustion air is sucked in through the intake holes 18 along with ignition, and the ignition and combustion of the fuel coal 30 are promoted.

[Effect of the invention]

 As described in detail above, the synthetic charcoal for barbecue of the present invention is arranged so that the ignition end of the ignition material is exposed with a gap in the lateral hole, so that it is easy to ignite and the flame is emitted from the lateral hole. Since the exhaust gas is introduced into the combustion chamber together with the outside air that is taken in, and the exhaust gas is exhausted from the combustion chamber through the exhaust holes, the ignition material does not generate smoke due to incomplete combustion at the early stage of combustion, and the ignition of the fuel coal is prevented. It is possible. Since the ignition material inside the combustion chamber is inserted with an air circulation space around it, when the ignition material starts combustion, not only through the lateral holes, but also at the bottom of the combustion chamber, which is provided as necessary, Fresh air also flows into the combustion chamber through the holes, and the combustion gas is exhausted through the exhaust holes, so the fuel coal is ignited quickly and reliably. In addition, the inflow of air from the lateral holes and the intake holes and the exhaust from the exhaust holes allow the combustion of fuel coal to proceed with appropriate thermal power without any special action.
